- 1. Field of the Invention
- The present invention relates to elevating chairs and more particularly to a mobile elevating chair apparatus that has particular utility in the care of individuals that have particular medical needs, including the need for assisted mobility and support.
- 2. General Background of the Invention
- There are a number of wheeled devices that are available to persons having particular medical needs, disabilities, injuries caused by trauma and the like. These chairs are available in many different forms. One of the most common forms is the well known wheelchair that can be either manually operable or motorized.
- Wheelchairs are very bulky devices that are hard to maneuver. They do not enable an individual to approach a table in virtually every restaurant or hotel situation for example.
- Many individuals have a desire to sit at a dinner table or to visit their favorite restaurant when dining out notwithstanding their particular medical condition.
- Several wheeled devices have been patented that attempt to solve the problems of providing transportation for individuals while providing improvements over the common wheelchair.
- As an example, the Pratt U.S. Pat. No. 2,609,862 discloses a hospital chair that has a triangular base with a single front wheel and two rear wheels, all of the wheels being positioned on the underside of the base. The Pratt chair includes a telescoping piston for elevating a chair that includes a seat back, seat base, and leg supports. The Pratt chair also includes armrests. A lever extends behind the piston for elevating and lowering the seat relative to the base.
- The Guyton U.S. Pat. No. 4,184,524 discloses a seat that is adjustable in height that includes a footrest and a base that has four radially extending members, each with its own foot.
- The Congleton U.S. Pat. No. 4,552,404 discloses a neutral body position chair that includes a base having wheels and a pedestal that telescopes to elevate and lower the chair. The chair includes seat base and seat back portions.
- A patient transfer device is shown in U.S. Pat. No. 5,438,722. The device includes a cushioned chair with wheels that facilities patient transfer in and out of a hospital clinical bed. The patient transfer device provides an entirely different method of transferring patients that avoids lifting the total body weight of the patient and that provides the maximum comfort for the patient.
- An ambulatory care chair is the subject of U.S. Pat. No. 6,089,593.
- The Harroun U.S. Pat. No. 6,220,620 discloses a wheeled height adjustable rehabilitation chair. The device includes a base having wheels that are steerable and a chair that sits upon the base with a pedestal. The wheels are located outboard of the seat to enhance stability, while the legs are positioned to provide a free space for the user's legs to facilitate user propulsion of the chair when the user is either sitting or standing. The seat chair is of narrow depth, allowing freedom of leg motion when the user is seated.
- Another elevating chair is shown in U.S. Pat. No. 6,296,310 that employs an actuator which is integral with a hydraulic cylinder that causes a piston to raise and lower.
- The Pratt U.S. Pat. No. 6,322,250 discloses an x-ray chair for providing support and comfort to a patient seated therein during an x-ray procedure.
- A design Pat. Des. 354,176 issued to Schwaegerle discloses a medical lift chair that appears to show a base, a hydraulic cylinder having a lever for operating the chair, probably to elevate it, and a chair that has armrests, a headrest and a footrest portion. The applicant is only aware of this design patent. However, it is noted that the patent is owed by Reliance Medical Products, Inc. of Mason, Ohio.
- The present invention provides an improved wheeled elevating chair apparatus. The device has a trapezoidal shaped base that includes an upper surface, a lower surface, and a periphery defined by a front edge, a rear edge, and a pair of side edges. The side edges form an acute angle. The rear edge defines the widest part of the base.
- A pair of rear wheels are mounted to the base at the rear edge.
- A pair of steerable front wheels are mounted to the base at the front edge, at least part of the steerable front wheels being mounted within the periphery of the base.
- Brakes are mounted on the pedestal and movable between released and locking positions, the rear wheels being locked to prevent rolling when the brakes are in the locking position.
- A pedestal is mounted on the base and extends vertically above the base upper surface, the pedestal including a plurality of pedestal members that telescope, at least one of said pedestal members being a first pedestal member attached to the base and a second pedestal member that is attached to the first pedestal member and elevates relevant to the base.
- A hydraulic jacking mechanism elevates the second pedestal member relative to the first pedestal member. The jacking mechanism includes a lever arm that extends from the pedestal rearwardly to a position that is above and behind the base.
- A chair is mounted on the pedestal, the chair including a seat base and seat back. The chair is able to change elevation relative to the base by moving the second pedestal member when the second pedestal member is elevated or lowered using the jacking mechanism.
- The lower arm elevates the chair when depressed and moved from a higher to a lower position and the chair and second pedestal member lower the chair when the lever arm is depressed to a lowest position and maintained in that lowest position.
